To all whom t may/concern.'

Be it known that I, JOHN M. FEDDERS, a citizen of the United States,residing in the county ofl Erie and State of New York, have invent-edlnew and useful Improvements in Radiators for Automob iles, of which .thefollowing is a specification.

In radiators for automobiles and the like as heretofore constructed aconsiderable amount of water was liable to be lost through the vent orautomobile tossed is a fragmentary vertical section of the upautomobileradiator provided per part of an .Fig 2 is a, horiw1th my improvements.

Fig. 3 is a detached side elevation for the guard of the filling tube.Fig. 4 is a perspective view of the guard for the vent and overflowpipe. l

Similar characters of reference indicate corresponding parts throughoutthe several views. V My improvements are applicable to various forms ofradiators for automobiles and the like, thatvshown in the example,comprising an upper Water header or box 1, a filling tube 2 projectingupwardly -from the top of this headerand communi-- cating at its lowerend with the interior of the same, a cover 3 for the upper end of theflling'tube which is detachably connectled with the latter by means ofan annular depending flange 4 forming part of the cover and having anexternal screw thread which engages with an internal screw thread 1 endof the filling tube, and ain the upper vent or overflow pipe 5 havingits upper or inlet end arranged vertically within the fillat W 'ters theupper end overflow pipe as the about in passing overV vrough roads andcaused the water jto splash drawings for ing tubev on one side thereofwhile its lower end extends to the exterior of the-radiator.

ter1or of theradiator and any. steam which is generated within theradiator by the heat from the engine also escapes to the exteriorthrough this pipe -which at this time serves as a vent for this purpose.

For the purpose of while being agitated in the radiator during thepassage of the automobile over rough preventing the water l' ater may beadded to the radiatorV from roads'from splashing upwardly into thelfillmgtube a guard device is provided for the same which preferablycomprises an imperforate body 6 of substantiallyy tubular form arrangedvertically within the filling tube and provided on one side with alongitudinal external groove 7 which receives the upper portion o thevent and overflow pip t its upper endv this imperforate tubular body. isprovided with a laterally projecting supporting flange 8 which isnormally clamped between At its lower end the body 6 1s provided with ascreen 11 extendlng horizontally across the same which screen ispreferably constructed of woven wire although th structed in any othersuitable manner.

VIn order to prevent any Water from splashing into the upper end of thevent and overflowl pipe and thus become wast-ed a the upper endv theguard device iaimvea guard device for this pipe is provided which'wardly facing internal shoulder, a cover for is preferably constructedin the form of a closing said filling tube having a depending cap 12which fits over the upper end of the flange which vis connected by ascrew joint vent and overdow pipe and forms therewith with the innerside of said tube and has its passages 13 which place the interior ofthe lower end facing said shoulder, a vent and water header incommunication with the overflow pipe arranged within said tube on ventand overflow pipe. rllhese passages are one side thereof, and a guardfor said tube preferably formed by providing the cylincomprising animperforate tubular body ardrical body of the vent and overflow guardranged upright within said tube and prowith longitudinal beads 141 whichare bent invided on one side with an external longitudiwardly and engagewith the exterior of the nal groove which receives said pipe, alaterventand overflow pipe, and traverse beads ally projecting flange at theupper end' of which are bent downwardly in the top said body which isclamped between said of this last mentioned guard and engage shoulderand the cover and which is pro- 15 with the upper end of the vent andoverflow vided with an opening for the passage of pipe, as shown inFigs. 1 and 2. rlhis vent said pipe and a screen arranged across the andoverflow guard is held in place fric lower end of said body.
